WOOD-HEEL MAINUFAGTURE.

Appleaton fi1ed January 7, 1928. Serial No. 245,085.

This invention relates particularly to the formation of the heel seats in the topsof the heel blocks.

At the present time these heel seats are usually formed ineither of two ways, the first method involving a barrel cutter to which the blocks are fed in a special holder, andthe second method involiing the use of a rotary rasp 01 toothed disc which cuts out the seat as the block is rotated over the same.

The first method is practical where a considerable number of the same size andstyle heels are to be seated, as the bolder must be specially made 01 set up for each size and style of heel and it only pays to do this when a greatnumber of the Same size and sty1e heels can be made up at onetime; The second method is used where a lesser number ofheels is to be operated on, but this method has the objection that after a first 'eut is made to removethe rim portion of the heel set, the machine must be readjusted and a second cut made to remove the centra-l portion of the seat.

Special objects of the present invention are to provide a machine suited to the latter class of work; that is, to the cutting of heel seats in dozen 1ots, more or 1ess, and which will be capable offinishing the heel seat complete in one and the Same operation The various nevel features of construction, combination and relation of parts by which the foregoing and other desirable objects are attained, will be apparent from the following specification.

The drawing accompanying and forming part of this specification illustrates one practical commercial embodiment of the invention, but as this is primarily for purposes of disclosure, it will be understood that the structure may be modified without departute from the true spirit and broad scope of the invention as hereinafter defined and claimed.

Figure 1 is a broken front elevation of the machine.

Figure 2 is a broken side view of the machine.

Figure 3 is a broken part sectional and diagrammatic view, illustrating the cooperative action of the two cutters which serve to about the central portion of the heel seat.

This central portion of the heel seat which is not removed by the first cutter is left in the form of a central ridge, as indicated at 9 111 Fig1ire 4:.

To secure the cooperative effect of the two cutters, the heel bleek 10 is guided over them after the manner md1cated in Figure 2, S0

that the smaller second cutter will operate on the central ridge portion 9 at the same time thatthe larger cutter 5 is taking away the surrounding outer-portion of the sent. This result is accomplished by bringing the heel seat face of the block against a face plate 11 overlying the cutters and having en opening 12 through which the rims o the cutters projeet and by the provision of a gage wheel 13 above the cutters against which the rim of the heel bleek is held while the block is turned to bring all portions of the heel seat into the range of the cutters.

The gage wheel is indicated as vertically adjustable by means of a screw stem 14 and the face plate is indicated as laterally 21djustable l y means of a carrier plate 15 which een be secured in laterally shifted adjustment by bolts 16.

The edge cutter is shown as carried by a spindle 17 mounted in fixed bearings 18 and operated by pulley and belt drive 19.

The smaller, center cutter 7 is shown as carried by a shaft 20 journaled in bearings 21carried by a sm all motor 22 and as driven through bevel gearing 23 from the shaft of this motor. T0 regulate the depth and rela tive position of the cut made by this cutter, the motor is shown as pivotally mounted at its upper cnd on a bolt 24, as secured in its pesitien of escillatable adjustment by a sec-uring bolt operating threugh an arcnate slot 26 in the base of the meter and the supplemental base 27 on which the motor is mounted is indicated as held in different positions of adjustment inelined te the vertical by belts 28 extending threngh slets 29 into the snpporting base er column 30.

In eperation, the heel is usually startcd as indicated in Figure 1, with one corner at the breast end of the bleek engaged with the euslyand eeeperatively remove the material te form the complete heel seat in one simple operation. 'Ihe setting of the gage wheel determines the approach of the edge of the heel bleek te the larger edge cutter and also what might be termed the centering of the heel bleek over the central cutter.

In praetise, the longitudinal center line of the heel bleek should be slightly efi' the center line of the cutter 7, as indicated in I ignre 2. The lateral adjustment of the laee plate 11 deterinines the depth of cut made b vthe edge cutter and also te an extent, the depth of cutmade by the center cutter. The latter, hewever, is susceptible of independent setting, beth by the swinging adjust-ment of the motor frame and by the inelined up and down bodily adjustment of the motor, which serve te regnlate the depth of cut and also the pesit-ien of sueh cut relative te the center line of the heel. The cuttere may be in the form of rotary ra sps such as indicated, and while shewn es ene larger than the other, it should be nnderstoed that they may be of the same size, er it fonnd desirable, the same may be reversed as te rela tive sizes. Other changes may be made te satist'y diferent requirements er conditions, all within the scope of the following claims. The adjustments disclosed enable the quick setting of the machine te practically any ditferent styles er sizes of heels and only this one setting is reqnired as the entire heel seat is formeel in the ene single eperatien.

What is clai1ned is:

l. machine 0i erming heel seats in weed lieels cemprising cutters positioned ene te trim away the edge portion of the heel seat and the. ether te simultaneously trim away the central portion of the same heel seet and inea'ns or guiding the heel seat laee ei a weed heel bleek irito preperly coeperating relation with said eutters.

guiding the heelseat 'ace of a weed bleek in coeperative relation therete.

2. A machine fer erming heel seats in weed heels comprising eutters pesitioned ene totrim eway the edge pertien ot the heel seat and the ether te simnltaneously trim away the central pertien of the same heel seat and means ter gniding the heel seat fa ce of a weed heel bleek into properly cooperating relation with said cutters, said guiding means and the cntters being relatively adjustable te efl'ect different positioning and depth of cuts made by the cutters.

3. In a machine of the character diselosed, & ztce plate ferming a support i:or a weed heel bleek, a gage everstanding said ace plate te pesit-ien the rim of a bleek hearing ageinst the face plate and relatively oflset retary cutters prejecting thr"eugh said ace plate into pesitien te eperate en diierent portiens of a heel bleck presented tothe face plate and gage means.

4. In a machine of the charaeter disclosed, retary cutters operating en difl'erent centers, ineens whereby said cutters may be relativly shifted te operate en different pertiens of a heel bleek presented thereto and gaging means t'or preperly presenting a heel bleek te said cntters.
